I feel as though some people spent many years doing painstaking, world class engineering work, and I paid them so that I could use it.

After I paid them they continued to support me videos and direct communication to help me use what I'd paid for, and they took seriously the problems I identified.

I'm sorry that you consider this being 'Robbed'. I had my car stolen once, and my house broken into another time, and those things didn't feel good.
